Inhibitory antibodies to two specific human and mouse Notch ligands, Jagged1 and Jagged2, are generated and shown to have beneficial effects in a goblet cell metaplasia asthma model; systemic Jagged1 inhibition transdifferentiates secretory cells into ciliated cells in the mouse, demonstrating that Jagged1 from ciliated cells normally holds back secretory cells to adopt the ciliated fate.
